Diodes Incorporated 74LVCE1G86SE-7

Overview

74LVCE1G86SE-7 from Diodes Incorporated is a single 2-input positive Exclusive OR (XOR) gate in SOT353 package, operating from 1.4V to 5.5V supply, with ±24mA output drive at 3.3V, 5.5V-tolerant inputs, and IOFF partial power-down protection. It performs Boolean Y = A ⊕ B and is used in voltage level shifting and parity generation circuits.

For engineers reviewing the 74LVCE1G86SE-7 datasheet, 74LVCE1G86SE-7 pinout, 74LVCE1G86SE-7 application, or 74LVCE1G86SE-7 equivalent, this device supports mixed-voltage interfacing, low-power logic translation, and signal isolation during system power sequencing-key considerations for embedded control and bus interface design.

Technical Context

The 74LVCE1G86SE-7 implements a standard totem-pole CMOS XOR gate with true positive logic function (Y = A·B̅ + Ā·B). Its IOFF circuit actively disables outputs during power-down, preventing back-current flow when V_CC = 0V.

Input voltage tolerance up to 5.5V enables direct connection to higher-voltage logic families (e.g., 5V TTL), while propagation delay ranges from 0.6ns (min) to 3.2ns (max) at V_CC = 3.3V and C_L = 15pF-enabling reliable operation in high-speed digital control paths.

FAQ

Can the 74LVCE1G86SE-7 operate reliably at 1.4V?

Yes. The device is fully characterized down to 1.4V V_CC, with guaranteed propagation delay (≤9.1ns at 1.5V, CL=15pF) and output drive (≥3mA at 1.4V). This enables use in energy-harvesting and ultra-low-power sensor nodes where supply rails dip near 1.4V during peak load.

Does the SOT353 package support thermal relief in PCB layout?

Yes. The SOT353 footprint uses standard 0.65mm pitch with 1.15–1.35mm body width and 0.9–1.0mm height. Diodes recommends land patterns per AP02001: 0.60×0.42mm pads with 0.25mm solder mask opening and thermal vias under GND (Pin 3) for improved heat dissipation in continuous 24mA drive scenarios.

How does IOFF behave when V_CC = 0V but inputs are pulled to 5V?

When V_CC = 0V, the IOFF circuit disables the output stage, limiting leakage current to ≤10μA even with 5.5V applied to A or B pins. This prevents back-current from unpowered sections into live 5V domains-a key requirement for hot-swap and modular power architectures.

Is the 74LVCE1G86SE-7 pin-compatible with other SOT353 XOR gates?

Yes, it shares identical SOT353 pinout (A-B-GND-Y-V_CC) with industry-standard single-gate logic devices including SN74LVC1G86 and 74LVC1G86. However, differences in V_CC min, IOFF support, and ESD rating require validation in partial-power-down and mixed-voltage contexts before substitution.
